.To all whom it may concern.-

Be it known thatI, EDGAR ALONZO HARVEY, a citizen of the United States, and a resident of Hillsboro Bridge, in the county of Hillsboro and State of New Hampshire, have invented a new and Improved Horse-Hoe, of

which the following is a full, clear, and exact description.

The purpose of the invention is to provide a construction of horse-hoe whereby the wings can be opened and closed more expeditiously and conveniently than heretofore and wherein the adjustment of the wings can be readily made while the hoe is in operation.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improved horse-hoe. Fig. 2 is a plan view thereof. Fig. 3 is a rear elevation, a portion of the hoe being in section; and Fig. 4 is a longitudinal vertical section taken practically on the line 4; 4 of Fig. 3.

A represents a hoe; B, the beam, which is attached to the hoe and to which the team is. 4 attached, and G represents the handles, which extend upwardly and rearwardly from the hoe A.

D represents the wings, which have a hinged connection 10 with a pilot extension A, located at the forward end of the body of the hoe A. The forward portion of the hoe is more or less pointed or triangular in front elevation, and the said pilot extension A is of corresponding shape. hinged to the rear ends of the pilot extension A can be carried outward or drawn inward, as occasion may demand.

A standard 11. is secured to the hoe A centrally of its rear end, and the said standard 11 is provided with a series of longitudinallyarranged apertures 12, located at or about its center, and is also provided with a slot 13 at its upper end portion.

A slide E is mounted for movement on the standard 11. This slide consists of a body portion 14:, an apertured head 16, and an ap ertured foot 15, the head and the foot being horizontal or at right angles to the body of The wingsD being the connecting member 14, as is best shown in Figs. 1 and 4:. The connecting or body member 14 of the slide E is provided with an aperture 17, capable of being brought into registry with any one of the apertures 12 in the standard 11.

The slide E is provided at its upper end or head portion with rearwardly-extending ears 18,'and between the said ears 18 a lever 20 is pivoted, the lower end of the lever extending down below the said ears, and at the lower end of the lever 20 a pin 21 is located, which pin normally extends through the aperture 17 in the slide E and through one of the apertures 12 in the standard 11, said pin 21 being thus held by a spring 22, which has bearing against the lever 20 and against the standard 11,.as is shown in Figs. 1 and 4, the said spring being coiled around a pin 23, which extends from the lever 20 into and through the slot 13 in the standard 11, a suitable washer being provided for the said pin 23 at the slot 13, and the forward end of the spring 22 has direct bearing on the said washer.

It will be observed that the slide E may be moved up and down on the standard when the upper end of the lever is pressed toward the standard, thus carrying the pin 21 out from the aperture 17 in the slide and the registering aperture in the standard, and at such time the lever 20 is moved up or down, as may be desired. This movement of the slide E is adapted to bring about a movement of the wings D either inward or outward, the wings being moved inward or in direction of each other when the slide is raised and outward or away from each other when the slide is lowered, and to that end connecting rods or links 19 are pivotally attached to the wings and to the foot member 15 of the slide, and after the lever 20 has been carried up or down to bring about a proper adjustment of the wings D the wings are locked in their adjusted position as soon as the lever is released, as the spring 22 will act to force the pin 21 into the aperture 17 of the slide and into the nearest aperture 12 in the standard. It is evident that the adjustment of the wings may be quickly and conveniently accomplished and that any required adjustment may be made without stopping the hoe. It is likewise evident that the adjusting mechanism for the wings D is exceedingly simple, durable, and readily operated, and the extent to which the slide E can be raised and lowered is governed by the length of the slot 13 in the standard.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In horse-hoes, Wings hinged to a hoe, adapted for movement to and from each other, a standard secured to the hoe, a slide operating on the standard, connecting-bars pivotally attached to the slide and to the Wings, and a lock-lever carried by the slide, through the medium of which lever the said slide is raised and lowered and locked in position.

2. In a horse-hoe, the combination with the body of the hoe having a pilot extension, and Wings hinged to the said pilot extension, of a standard secured to the rear portion of the hoe, having a series of apertures between its ends and aslot at its upper end, a slide mounted on the standard, having an aperture adapted to register with an aperture in the standard, links pivotally connecting the slide with the said wings, a spring-controlled lever carried by the slide, having an extension which enters the slot in the standard, and a pin which enters the aperture in the slide and an adjacent aperture in the standard.

3. In a horse-hoe, the combination of the body, wings hinged at their forward ends to the body, a standard secured to the rear of the body and having a slot in its upper end and a'plurality of apertures intermediate of .its ends, an apertured slide mounted on the EDGAR ALONZO HARVEY.
